Pharmacological properties
Pharmacodynamics
The active component of Venter is sucralfate disaccharide, which contains sucrose sulfate and aluminum hydroxide. This compound promotes rapid healing of peptic ulcers, prevents the development of gastric ulcer and duodenal ulcer, protects the mucous membranes of the gastrointestinal tract from the effects of hydrochloric acid and pepsin.
Sucralfate reduces the activity of pepsin by about 30%, while minimally affecting the acidity of gastric juice. The substance binds to protein compounds of the affected tissues of the mucous membranes, which leads to the formation of a protective film on the surface of the ulcer. Venter accelerates the regeneration of damaged areas of the mucous membrane, improves scarring of ulcers and is used to prevent recurrence of peptic ulcer disease, including as a result of stress. It also reduces the absorption of phosphates in the digestive tract.
Pharmacokinetics
When taken orally, Venter is slightly absorbed and enters the systemic circulation. In plasma, clinically significant concentrations of the drug are not detected, the systemic effect is also not detected. Sucralfate is not involved in metabolic processes. Venter is partially excreted through the kidneys, and the remainder is excreted unchanged through the intestines.
Indications for use
- Reflux esophagitis;
- Hyperacid gastritis;
- Gastroduodenitis;
- Peptic ulcer of the stomach and duodenum in the acute phase;
- Symptomatic ulcers;
- Reflux gastritis;
- Stress ulcers and erosive and ulcerative lesions of the gastrointestinal tract associated with the use of non-steroidal anti-inflammatory drugs;
- Medicinal ulcer;
- Hyperphosphatemia in patients with uremia on hemodialysis;
- Heartburn.
Contraindications
- Severe renal dysfunction;
- Bleeding from the gastrointestinal tract;
- Obstruction or dysphagia of the gastrointestinal tract;
- Hypersensitivity to drug components.
Venter should be used with caution in nursing and pregnant women.
Instructions for use of Venter: method and dosage
Venter for adults is usually prescribed by mouth at 0.5-1 g, the frequency of administration is 4 times a day. Also, the drug can be taken 1 g 2 times a day (morning and evening) or 2 g 2 times a day 1 hour before meals and before bedtime.
The maximum daily dose is 12 g. The average duration of peptic ulcer therapy is 4-6 weeks, if necessary, up to 12 weeks.
In patients with hyperphosphatemia, with a decrease in plasma phosphate concentration, the dosage can be reduced.
For children, the drug is prescribed 0.5 g 4 times a day.
The tablets can be swallowed whole with a liquid, or, like granules, dissolved in 1/2 glass of water before taking.
Side effects
According to the instructions, Venter can cause the following side effects:
- Central nervous system: dizziness, drowsiness, headache;
- Digestive system: diarrhea, constipation, dry mouth, nausea, gastralgia;
- Dermatological reactions: urticaria, rash, pruritus;
- Others: pain in the lumbar region.
Overdose
Usually, patients tolerate Venter treatment well, therefore, cases of overdose are extremely rare. However, when taking the drug in significant doses, allergic reactions may occur, which are the result of individual sensitivity to sucralfate. Such conditions are characterized by the appearance of a skin rash, irritation of the skin, pain in the abdomen, nausea and vomiting. In this case, symptomatic therapy is prescribed.
With prolonged Venter therapy, patients with renal insufficiency may develop intoxication with aluminum, among the significant consequences of which is osteomalacia or encephalopathy. In this case, the drug is immediately canceled, hemodialysis, peritoneal dialysis and hemofiltration are performed as treatment, and deferoxamine is also administered.
special instructions
If necessary, the simultaneous use of Venter with antacids, they should be taken half an hour before or half an hour after taking the drug.
The appearance of seizures and drowsiness may indicate toxic effects of aluminum.
In renal failure, serum phosphate and aluminum concentrations must be monitored.
Short therapy can lead to complete scarring of the ulcer, but Venter's administration does not change the severity and frequency of recurrence of peptic ulcer disease that occurs after scarring.
Drug interactions
With the simultaneous use of Venter:
- A decrease in the anticoagulant activity of indirect anticoagulants (including warfarin) is possible;
- The absorption of antimicrobial agents of fluoroquinolone derivatives, digoxin, tetracycline, sulpiride, phenytoin, and amitriptyline is reduced, which can lead to a decrease in the clinical effectiveness of the latter;
- The effectiveness of levothyroxine is markedly reduced;
- Some decrease in bioavailability of ranitidine, cimetidine, roxatidine is possible;
- The concentration of quinidine in the blood plasma decreases;
- Minor changes in theophylline pharmacokinetics are observed. It is also possible to significantly decrease the absorption of theophylline from sustained-release dosage forms;
- A slight decrease in the absorption of fluconazole and ketoconazole is possible.
It is believed that when used together, the formation of chelate complexes with tobramycin sucralfate, colistin sulfate, amphotericin B is possible, which can lead to a decrease in their antimicrobial activity.
